The locking claw 5c comes into contact with the back seats of the hinge bodies 21 and 31.

  When the assist grip is attached to a predetermined position in the interior of the automobile, the hinge portions 2 and 3 at the bases on both sides thereof are pushed into rectangular holes (not shown) provided in the molded ceiling material and the body panel. At this time, the bulging portions 5b and 5b of the mounting clips 5 and 5 hit the edge of the rectangular hole and enter the rectangular hole while being elastically deformed inward (in the direction of reducing the width). When the bulging portions 5b and 5b are completely fitted into the rectangular holes, the edge of the rectangular hole of the body panel between the locking portions of the bulging portions 5b and 5b and the seats at the tips of the hinge bodies 21 and 31. Is sandwiched and locked.

  Thereafter, the covers 4 and 4 that have been temporarily fixed are pressed against the front surfaces of the hinge bodies 21 and 31, and the locking claws 43 and 43 on the inside thereof are pressed against the cover locking portions 29 and 29 on both sides of the hinge bodies 21 and 31. Fit into 39. In this state, the clip support portions 42 and 42 of the covers 4 and 4 are completely fitted inside the attachment clips 5 and 5, and the attachment clips 5 and 5 are firmly locked to the body panel to attach the assist grip. To complete.

  When the assist grip is used, the user rotates the grip body 1 downward with respect to the left and right hinge portions 2 and 3 as shown in FIG. The grip body 1 is pulled downward at the center by the user. At this time, the torsion coil spring 6 has its other end 62 turned by the rotation of the locking recess 11 a of the hinge recess 11 in the grip body 1. It is twisted against the force and moves in the guide groove 73 of the spring case 7. As a result, the grip body 1 rotates downward against the torsion spring force, and the grip body 1 is used when the user grips the grip body 1.

  At this time, the load applied by the user is applied to the inner boss 24, the support shaft 34 and the outer bosses 25, 35 of the hinge portions 2, 3 via the grip body 1, but mainly downwards with respect to the inner boss 24 and the support shaft 34. A large load is applied.

  However, this load is received by the inner boss 24 and the support shaft 34 projecting from the thicker inner support pieces 22 and 32, and the support member is interposed between the inner support pieces 22 and 32 and the outer support pieces 23 and 33. Since the spring case 7 or the oil damper 8 is inserted, the inner boss 24, the support shaft 34, and the inner support pieces 22 and 32 can be reliably supported without being bent.

  Also, the load at the time of use is applied mainly to the upper portion of the outer bosses 25 and 35, but the notches 25a and 35a provided in the outer bosses 25 and 35 are only the lower end portions of the outer bosses 25 and 35. Since the boss hole wrap amount with respect to is sufficiently secured, the outer bosses 25 and 35 can reliably support the load in use at the upper part thereof. Similarly to the above, since the spring case 7 or the oil damper 8 is inserted between the inner support pieces 22 and 32 and the outer support pieces 23 and 33 as a support member, the outer bosses 25 and 35 receive a load. The outer support pieces 23, 33 are prevented from being bent and deformed.

  On the other hand, when the user removes his / her hand from the grip body 1 in the use state of the assist grip, the grip body 1 is attached upward (counterclockwise in FIG. 2) from the other end 62 of the torsion coil spring 6 in the spring case 7. Under the influence of the force, it rotates in the same direction and returns to the non-use state (solid line position in FIG. 2). At this time, the oil damper 8 acts to brake the rotation of the grip body 1, and the grip at a low speed. The main body 1 will return to the non-use position.

  In the above embodiment, the engagement portion 33 a is provided on the inner side surface of the outer support piece 33 in the pair of inner support piece 32 and outer support piece 33 of the hinge portion 3. It can also be provided. In this case, the gear portion of the inner cylinder of the oil damper is provided at the end opposite to the end of the oil damper 8 in FIG. Moreover, the hinge part which attaches an oil damper can also be made into the hinge part on the opposite side to the said embodiment.
